That's a reasonable hypothesis, but the car I just drove to Co.
Springs was stored for 2 years in my unheated garage. I parked it
with a nearly full tank, which was about 3/4 full when I got it back
out. It started right up with the 2 year old gasohol, and ran
perfectly for the 2300 mile trip. I don't think there was a
significant amount of water in there.
My only problems were a couple of very small gas leaks, including one
that I've still not found. I can only smell it.... ;-p

This, along with changing barometric pressure, is absolutely true,
but it applies to any kind of fuel.
